Laminate Load Beam With Trench Arrangement Having Circuit Housed Therein

View page
US Patent:
7019946, Mar 28, 2006
Filed:
Jun 27, 2003
Appl. No.:
10/607685
Inventors:
Richard August Budde - Plymouth MN, US
Keefe Michael Russell - Robbinsdale MN, US
Assignee:
Seagate Technology LLC - Scotts Valley CA
International Classification:
G11B 5/48
G11B 21/16
US Classification:
3602443, 3602459
Abstract:
A disc drive has an improved electrical interconnect assembly mated to a suspension assembly for coupling one or more conductive paths leading from a read/write head to control circuitry located off the suspension assembly. The interconnect assembly has a portion that extends along an edge of the suspension assembly that is oriented towards the outer diameter of a disc on the disc drive. The suspension may be made of a laminate material and may include a trench formed in the suspension that is configured to mount a portion of the interconnect assembly. Positioning a portion of the interconnect assembly on the edge of the suspension towards the disc outer diameter and mounting another portion of the interconnect assembly in a trench formed in the suspension assembly reduces windage-induced vibrations of the suspension assembly and, consequently, the head.

Mar 2, 2009
Appl. No.:
12/395933
Inventors:
Jon Klarqvist - Roseville MN, US
Keefe Russell - Robbinsdale MN, US
Assignee:
Seagate Technology LLC - Cupertino CA
International Classification:
G11B 5/48
US Classification:
3602459, 3602452, 3602453
Abstract:
Head gimbal assemblies for data storage systems are provided. Some embodiments include a dielectric layer having a first and a second side. A first conductive layer is on the first dielectric layer. The first conductive layer includes a pad and a trace. A second conductive layer is on the second dielectric side. A via extends from the first dielectric layer side to the second dielectric layer side. The via electrically connects the first conductive layer to the second conductive layer.

Slider-Gimbal Scratch Mitigation

View page
US Patent:
8300362, Oct 30, 2012
Filed:
Jun 15, 2009
Appl. No.:
12/484816
Inventors:
Manish Virmani - Eden Prairie MN, US
Paritosh Chandrakant Panchal - Bloomington MN, US
James Fisher - Chaska MN, US
Keefe Michael Russell - Robbinsdale MN, US
Sandeepan Bhattacharya - Eagan MN, US
Assignee:
Seagate Technology LLC - Scotts Valley CA
International Classification:
G11B 5/48
US Classification:
3602453, 3602457
Abstract:
A head gimbal assembly for use with a load beam includes a gimbal, a slider for carrying a transducing head, and first and second tabs. The gimbal is configured to be supported by the load beam, and includes a gimbal tongue. At least a portion of the slider is secured to the gimbal tongue. The first tab extends from the gimbal tongue proximate a first corner of the slider. The second tab is spaced from the first tab and extends from the gimbal tongue proximate a second corner of the slider.

Protective Layer On Gimbal For Scratch Mitigation

View page
US Patent:
8493689, Jul 23, 2013
Filed:
Jun 15, 2009
Appl. No.:
12/484828
Inventors:
Manish Virmani - Eden Prairie MN, US
Paritosh Chandrakant Panchal - Bloomington MN, US
James Fisher - Chaska MN, US
Keefe Michael Russell - Robbinsdale MN, US
Sandeepan Bhattacharya - Eagan MN, US
Assignee:
Seagate Technology LLC - Scotts Valley CA
International Classification:
G11B 5/48
US Classification:
3602453, 360245
Abstract:
A head gimbal assembly includes a gimbal, a slider, and a polymer layer. The gimbal comprises a metal layer, and the metal layer of the gimbal defines a gimbal mounting portion for attachment to a metallic load beam and a gimbal tongue extending from the gimbal mounting portion. The slider comprises a ceramic material for carrying a transducing head, and at least a portion of the slider is secured to the gimbal tongue. The polymer layer is positioned adjacent to the gimbal and configured for limiting ceramic-to-metal and metal-to-metal contact.

Flex On Suspension With Actuator Dynamic Function

US Patent:
20030043508, Mar 6, 2003
Filed:
Apr 17, 2002
Appl. No.:
10/124895
Inventors:
Kevin Schulz - Apple Valley MN, US
Keefe Russell - Robbinsdale MN, US
Saoudy Saoudy - Eden Prairie MN, US
International Classification:
G11B005/48
US Classification:
360/245900, 360/264200
Abstract:
A disc drive comprises an improved electrical interconnect for connecting the head to read/write circuitry on a printed circuit board. A single-cable interconnect has both head suspension capability and dynamic loop function. A pre-amplifier can be connected at either the printed circuit board or mounted on the interconnect. The present invention has improved electrical performance, improved reliability, and lower assembly cost compared to a dual-cable interconnect.

Low Electrical Impedance Slider Grounding

View page
US Patent:
20030128474, Jul 10, 2003
Filed:
Jan 28, 2003
Appl. No.:
10/352602
Inventors:
Kevin Schulz - Apple Valley MN, US
Keefe Russell - Robbinsdale MN, US
Michael Gronseth - Bloomington MN, US
International Classification:
G11B005/48
US Classification:
360/245900
Abstract:
An improved suspension assembly comprises a suspension, a slider and a ground trace. The suspension includes a load beam and a gimbal connected to a distal end of the load beam, the gimbal having a slider opposing face. The slider supports a transducing head and the slider supported by the slider opposing face of the gimbal. The slider includes a slider body having a gimbal opposing face and a disc opposing face, the slider body having a forward face extending between the gimbal opposing face and the disc opposing face. A slider bond pad and a slider ground pad are located on the forward face of the slider body. A ground trace is interconnected with the slider ground pad.

Adhesive Control Features For Disc Drive Head Suspension And Flex Circuit Interconnect

View page
US Patent:
6738226, May 18, 2004
Filed:
Aug 3, 2000
Appl. No.:
09/631530
Inventors:
Sandeepan Bhattacharya - Bloomington MN
Shri Hari Narayan - Minneapolis MN
Rich Lawrence Segar - Eagan MN
Keefe Michael Russell - Robbinsdale MN
Assignee:
JPMorgan Chase Bank - New York NY
International Classification:
G11B 548
US Classification:
3602459
Abstract:
The present invention provides a system, method and apparatus for controlling the coverage of an adhesive bond area between a suspension and a flex circuit interconnect by etching an area of the suspension to create a bonding area. The etching process prevents bonding of the flex circuit interconnect to the suspension in a tail and a side region allowing movement between the flex circuit and suspension, wherein the movement dampens a first torsion resonance mode. Better control of the bonding area between the interconnect and the suspension using the âadhesive downâ helps reduce the variation in the roll stiffness of the suspension thereby reducing the fly height variation.
